Big Dog couldn't handle their big men when they went to the perimeter. They shot well enough to make him have to come out on them, but then had the speed to go around him when he came out. Poke is in a much better position athletically to handle that situation. I think Keith also knew Big Dog was he was getting gassed and wanted to save his energy for the offensive end.
I honestly couldn't tell you the last team we had that was decent at defending dribble penetration. Maybe it's something the Zips defensive strategy sets them up for.
A couple of defensive things I've noticed and would like to see modified. First, we trap the ballhandler every time on a high pick. We never switch it (until after the trap) or just play through the pick. As a result, we're vulnerable to a team that moves the ball finds the big man quickly coming off of the pick. Also, I don't recall seeing a second of zone this year. I'm not a bog fan of the zone, but It is something we ought to trot out occasionally, even for a couple of possessions, for a different look.

I sit in the very last row of the GA stands, as close to the middle of floor, for every game. On many occasions during a given game, I stand to cheer on the team in an important point in the game. I'm always amazed at how often there's nobody else standing between me and the distant floor. The only thing that gets the casual UA fan/attendee on their feet is the guy in front of them standing up.
Hmmmm, you know what? UA should give me front row seats. I could start the avalanche that gets every up on their feet cheering!

Zeke was the ultimate "you don't know what you've got 'til it's gone" for me. He drove me bonkers for 4 years, but the second he wasn't on the floor for the Zips, I realized just how valuable he was. With our perennial inability to stop dribble penetration, he was the perfect solution. He eventually became decent on defense. RIght now, he gets my vote. That may change in the next couple of months, but for now, I vote Zeke.
